apparatus or still constructed and adapted to operate substantially asshown and described and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of the apparatuspartially broken away at the top, and Fig. 2 is a cross section thereofon line 2-2, Fig. 3. Fig. 3

is a front elevation partially broken away top and bottom, and Fig. 4 isa vertical sectional elevation on a line corresponding to 4-4:, Fig. 3.r

The apparatus as thus shown is designed to be connected with a waterservice pipe to maintain the water supply and has two overflows oroutlets, one for the cooling water in the respective jackets and anotherfor the condensed water.

Structurally the invention comprises a water distilling boiler B, twocooling jackets J and J and a steam condensing chamber 0 between thesame having an outlet 2 at its bottom for the distilled water. Entrance'of the water to the apparatus is by inflow or supply pipe 3 to the saidjackets which, while being distinguished herein by different referencecharacters for convenience of description, in fact are one continuousjacket as seen in Fig. 2. The said condensing space lies within and issurrounded by this jacket and opens into the upper portion of the boilerover an inwardly curved Wall 8 at the front and top of said space andapart from the dome D of the boiler; This wall also serves toconfine'the water in the boiler at its rear. As the steam is evolvedfrom the shallow layer 9 of water on the bottom 6 of the boiler itnaturally rises above and rolls outward over the said wall 8 and asitcomes into the presence of the cool surfaces or walls of the space Cnaturally condenses and runs down and out at spout or pipe 2. The supplyof water to the boiler is from the top of the outer jacket- J throughorifices or openin's 4 in the wall of dome D, and the level 0 the waterin the jackets and boiler is fixed at one side of the rear coolingjacket J .by overflow wall 5, where the water drops lnto the vertlcaland separately walled assage 6 and passes down to outlet pipe g at itsbottom. This maintained level precludes possible flooding of the boilerwith water beyond the comparatively shallow depth shown and quicklyresponds to the heat from burner B. The bottom of the boiler is flat andlevel and the burner B a bracket '6' centrally beneath said bottom andcarried by the front wall of the water acket. The burner may be of anypreferred form or construction.

The dome D of the burner isprovided with a central flanged opening inits top which is closed by a steam tight cap d seated upon and withinaid flan e and concave on Its inner surface to conform exactly to thecurvature or contour of the inner surface of the dome and to be flushtherewith all around, screws 10 serving to look said cap in place. Cap(1 is removable to permit cleansing of the interior of the boiler.

Now, the semi-elliptical shape or outline of the boiler andpart-circular form of the cooling jackets and condensing chamber isdeemed to be material to the mvention for several reasons. In the firstplace, it works economy in generating the steam by reason of itssemi-elliptical and circular shape with the burner at the middle, and itespecially promotes rapidcondensation by reason of the free access ofthe condenser space to the interior of the boiler and the largecondensmg area, and for the further reason that the semi-elliptical domeeliminates all dead ends and pockets. Furthermore, the vapor pressure inthe boiler is maintained below normal by reason of the rapidcondensation due to the construction described. A maximum of efficiencyin condensation is the result. Then again by having'the entire dependingportion of the apparatus curved to a segment with the back to the rearor wall the heat is not only confined thereby about the rear but anoutward deflecting surface is provided for the -heat and such flame asthere may be away' from the wall. It is to be observed that thisapparatus is comparatively small and is designed to be hung upon a wallor partition or the like, and hence it is material to so construct thedevice as to absolutely prevent catching fire therefrom.

Further detailed reference disclosesthat the inner jacket J stopsbeneath the bottom is supported on of the boiler while the outer jacketextends above said bottom somewhat and has its high water mark levelwith the top of the water in the boiler but with its outer wall 7Vextending abovethe lower portion of the dome. Ina sense there are fourwalls and in another sense there are but two. Thus, the outer wall maybe defined as that wall which extends around the entire waterjacket.while the inner wall W extends around the condensing space and alsoconstitutes .the inner wall of the jacket or jackets. In cross sectionthese walls also are four in number whenthe spaces bounded by them areconsidered. It will be seen that this portion of the apparatus isvertical while the boiler projects-forward from the top thereof afterthemannerof a canopy in point of appearance, but of evident utllity infact. Ears or extensions 15 and 16 top and bottom respectively serve tosupport the apparatus on the wall, and the bottom ear is slotted topermit fastening of the apparatus in true vertical alinement, using ascrew or other fastening device.

In my invention I have accomplished the maintenance of a constant waterlevel in .the boiler by an overflow within the cooling jacket J andsmall feed openings direct from the cooling jacket J to the boiler B,thereby eliminating any and all exterior tubing connections or cupsemployed in other known devices to accomplish the same result.

The bottom ofcondensing chamber 0 is inclined downwardly from. each sideto the:

center and also forward to romote selfdrainage, and a vertical divisionwall 17 within jacket J the full depth thereof separates the intake sideat intake? from outlet passage 6, thereby causing a circuitous flow ofthe Water around the front and back of chamber C fromthe bottom to thetop. A small'vent openin 18 is also provided in the top of jacketglabove passage 6. Oh viously, valved pi es or faucets'may be used in lieuof the (p ain intake and discharge pi es shown an described.

. at I claim is:

1. A water distributing apparatus having a boiler with a flat bottom anda domeshaped top closing down about the said bottom, a condensing spacesegmental in cross section inclosed about its top by said dome and awater jacket segmentally shaped to conform to said condensing space andhaving a discharge opening in its outer portion into said boiler nextbeneath the dome therein. 7

2. A distilling apparatus consisting of a boiler having a flat bottomand a domeshaped top of greater area at its bottom portion than saidbottom, a condensing s ace segmental in cross section depending rom atits inner edge over which the steam is adapted to pass into said space,and a water jacket about said space the full depth thereof and providedwith an outlet at its top and outer portion through the wall of saiddome on a level above the boiler bottom.

3. In a water distillingapparatus, a circular boiler of semi-ellipticalcross section and a steam condensing chamber depending from one sidethereof and-a water-cooling jacket about the same forming a side portionof the boiler, said jacket and said condensing chamber being segmentalin cross section and of uniform depth transversely, whereby a largecondensing area is provided. Y

4.In a water distilling apparatus, a boiler and a segmentally shapedsteam condensing chamber vertically at the rear thereof and open theretoat its top, and watercooling jackets front and rear of said chambersegmental shape in cross section and having water communicating openingswith the boiler above the bottom thereof and an overflow outlet fromsaid boiler to maintain a shallow depth of water therein.

5. .In a water distilling apparatus, a boiler having a steam condensingchamber open thereto at its rear and a water jacket encirclin saidchamber having an inlet and an out et at its bottom and rovided with adivision wall between said mlet and outlet and alsoan overflow wallparallel with said division wall to maintain a fixed level of water inthe boiler and jacket and promote a circuitous flow of water around thefront and back of said chamber from bottom to top thereof.

In testimony whereof I afiix my signature in presence of two witnesses.
